The Jean-Boivin River is accessible by the route 175; other secondary forest roads have been developed in the sector for the needs of forestry and recreational tourism activities.[1][2][3]

Forestry is the primary economic activity in the sector; recreational tourism, second.

The surface of the Jean-Boivin River is usually frozen from the end of November to the beginning of April, however the safe circulation on the ice is generally made from mid-December to the end of March.

The Jean-Boivin River rises at the mouth of Petit lac Richelieu (length: 0.35 km (0.22 mi); altitude: 584 km (363 mi)). The northern mouth of the lake is located at:

• 2.4 km (1.5 mi) west of the course of the Normand River;
• 3.4 km (2.1 mi) north-east of a curve of the Petite rivière Pikauba;
• 3.2 km (2.0 mi) north-west of Lac Grimard;
• 8.1 km (5.0 mi) south-west of route 175;
• 12.2 km (7.6 mi) south of the confluence of the Jean-Boivin river and the Cyriac River.[1]

From little Richelieu Lake, the course of the Jean-Boivin river flows over 18.1 km (11.2 mi) entirely in the forest zone, with a drop of 334 km (208 mi), according to the following segments:

• 0.5 km (0.31 mi) towards the west, in particular by crossing on 0.4 km (0.25 mi) Lake Richelieu (length: 0.6 km (0.37 mi); altitude: 579 m (1,900 ft)), to its mouth;
• 0.8 km (0.50 mi) towards the northwest in particular by crossing on 0.3 km (0.19 mi) Boivin Lake (length: 0.5 km (0.31 mi); altitude: 524 m (1,719 ft)), to its mouth;
• 1.4 km (0.87 mi) north-east in a deep valley to the outlet (coming from the north) of lakes Eve and Adam;
• 2.3 km (1.4 mi) north-west, to the outlet (coming from the west) of Lac Lavade;
• 6.8 km (4.2 mi) towards the north in a deep valley at the start of the segment and leaving mid-segment of the territory of the Laurentides Wildlife Reserve, up to the confluence (coming from the 'west) of the Petite Rivière Jean-Boivin;
• 3.9 km (2.4 mi) north, then northeast, to Filion stream (coming from the south);
• 2.4 km (1.5 mi) towards the north-east in a deep valley, then bending towards the east to go around a mountain, to its mouth.[1]
